I2C problems - jlazkano - 2021-08-26 Hello, I try to connect some I2C sensors. Yesterday the MPU 9250 works for some hours, but now I can not get it working. The I2C app say "I2C enabled stoped": When I disable the I2C interface in the Raspberry Pi setting, I get this in dmesg: PHP Code: [ 534.089750] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /soc/i2c@7e804000/status And this when I enable it again: PHP Code: [ 538.246301] i2c-bcm2835 3f804000.i2c: i2c transfer timed out Is something wrong with my Raspberry Pi 3B device? How could I start the I2C module? Kind regards. RE: I2C problems - jlazkano - 2021-08-27 Hello, I burn the OpenPlotter image in a new SD and try to configure the I2C sensor, same result: Is my Raspberry Pi broken? Could I debug it deeper? I will appreciate your help. Regards. RE: I2C problems - jlazkano - 2021-09-01 Hello, I still have the I2C not running message, but I fixed the MPU sensor detection with this commands: PHP Code: sudo systemctl enable openplotter-i2c-read.service Hope this will help to someone else.
